In this study, we report a hydrothermal method for the preparation of La-2(MoO4)(3) with a hierarchical nanostructure consisted of nanosheets. The influences of heating times on the products were also investigated. The products were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM), and X-ray photoelectron spectroscopy (XPS). The potassium sodium tartrate plays a key role in the formation of hierarchical nanostructures. The potassium sodium tartrate was used as a chelating ligand and a template molecule in the synthesis and self-assembly of nanosheets. In view of experimental results, a possible formation mechanism of these hierarchical nanostructures in the growth processes was proposed. This synthetic strategy was also successfully applied to fabricate KNd(MoO4)(2) with the hierarchical nanostructure.
